Accessibility probability versus the threshold for: a dRSRP and b λ. Figure depicts the relationship of accessibility probability with threshold. a shows the change of their relationship in different conditions; red, yellow, brown and blue lines are the cases where downlink reference signal received power is equal to 5 W, 4 W, 3 W and 2 W, respectively. b shows the cases of uplink reference signal received power impact factor is equal to 0.1, 0.5, 1 and 5
